21. Starting G-code for Cura after BLTouch installation
1 min readJul 2, 2020
My tinkering with BLTouch has just started. Here is the start G-code which is added in the Printer Settings. This is a mix of code that was already there in Cura and a code that was originally posted in this Reddit thread.
